I have a very irregular period by the way

Worrying too much will delay your period. If the test was Negative you shouldn't worry too much.

Really... you mean all those fictitious "sysmptoms" that nearly all children. Old women AND Men get from time to time, and not just women during their child bearing years?

I haven't seen any indication of the only symptom that matters... being late for a period. What you descided was a period... no matter how irregular you might be... its nowhere near being late for one... much less being the two weeks late for one you need to be for a test to be remotely accurate.

There are no signs that you should be having at this point and time. The only first sign is a missed period. So I have no idea what other "signs" you think you should have. A heavy period, is not late.

Also, it is far too early to test. You wait and see if you have your next period. If you have it, you are not pregnant. If you don't have it, then you test.
